A wide-field astrophotograph of the Pleiades star cluster (M45) shows brilliant blue stars surrounded by glowing blue nebulosity. Wisps of dust appear to stretch like mist around the cluster. A soft red glow from hydrogen gas surrounds the outer edges, creating a vivid contrast against the dark backdrop of space.

Stunning image of NGC 1435, a reflection nebula surrounding the star Merope in the Pleiades star cluster. The nebula's blue hue is due to blue light scattering more effectively off carbon dust grains than red light. The brightness is determined by grain size, density, and the star's properties. This celestial sight showcases the beauty of interstellar dust reflecting starlight.
